Whats wrong with a soekris and an Motorola Oncore following the
recepy of Poul-Henning's  http://phk.freebsd.dk/soekris/  Using a
soekris with PCI-slot should work with Heikos fine receivers as well,
or the lately popular Garmin 16LVC (?).

That does indeed sound like a good idea, and I am not saying there is anything wrong with it. As it happened for me at the time,it was easier simply to re-use an existing old PC (Pentium 133 with 48MB of memory).

These antennas are reradiating kits. Their receiving antenna is no
different from a normal active antenna. Passive antennas does not work
with small diameter coax cable longer than a few decimeters. So if
your standart GPS antenna has 3 or 5 meter coax cable attached you
can be sure its an active/amplified antenna with internal LNA (Low
Noise Amp.).

I find that these antennas give adequate reception in my top-floor
location.

Try with your standard antenna, if that does really not work. Try
getting another with a higher gain LNA.

Björn,

I think re-radiating is not a good description, as these devices are passive at RF. The "active" component is indeed a built-in LNA like you say.

My standard antenna in this top-floor location is the active antenna I described. The Garmin GPS 18 LVC I have seems less sensitive than the GPS 12 XL with an active antenna. Of course, there is /no/ external cable between the antenna of the GPS 18 LVC and the RF and electronics module, it is all built into one unit. There is no concept of being able to plug an external antenna into the GPS 18 LVC.

Thanks for your comments.

David
